Hi Miguel, we appreciate your feedback and hope you are enjoying the BIMWorkplace!

• At this point, it is possible to import not only sheets, but also "floor plans". To import the model with these views, you need to define some settings in your source software. In Revit, go to Collaborate > Publish Settings tab > open the "show in list" drop-down > select the option "all views and sheets in the model" > then you can choose which views you want to import to BIMWorkplace and finish with "save & close". You can see the first image attached to the comment.
Once you have made this, you can import your model with the selected views.

• As for your second question, at this time, we do not have an implementation date for this split-screen view feature. For now, we have this split screen options in the second attached image.
Thank you for your suggestion. We may work on this feature in the future to improve BIMWorkplace.
